Bio Energy: Sun + CO2 + water = syngas
A team of researchers at the ETH Paul Scherer Institute and the California Institute of Technology (Caltech) has developed a thermochemical reactor of a new genus.
It is indeed able to transform, through the sunlight, a mixture of water and CO2 into a synthetic gas, the syngas. This gas is the basis of liquid fuels like gasoline or kerosene.
This reactor is the latest in a multitude of projects aimed at finding new sources of energy. But if these projects are many, few will ultimately find practical application. Wednesday, February 9, 2011

The process reactor Swiss-American is described as promising, even if it has a yield of 0.8% in Switzerland, at low altitude is to say that the amount of energy as fuel it produces is equivalent to less than one percent of solar energy it uses for production.

But the principle is there and Professor Aldo Steinfeld
, Institute of Energy Technology at ETH Zurich is confident that developments are possible.
Fairly projects for the same purpose (finding new sources of energy) have recently emerged in recent years. Massimiliano Capezzali
, deputy director of the EPFL Energy Center, says though many of them will be implemented and when.

- Norway opened on 24 November 2009 the first prototype osmotic power plant world. This new technology sustainable uses the principle of osmotic pressure, ie the reaction obtained by the encounter between freshwater and saltwater. The energy thus obtained should eventually enable countries with access to the sea to reduce their dependence on fossil fossiles.Thierry Fischer described this process already used by man to desalinate seawater Knowledge on RSR

New research published in "Global Change Biology " shows how bioenergy can replace gasoline with biofuels from a process involving the conversion of waste and thus reduce global CO2 emissions to 80%.
biofuels produced from crops have been controversial because they require an increase in agricultural production leading to the passage of serious ecological consequences. The second-generation biofuels such as cellulosic ethanol derived from municipal waste could offer an alternative without compromising the environment. 
According to the study author, Professor Hugh Tan, National University of Singapore "
According to the study author, Professor Hugh Tan, National University of Singapore " our results suggest that the fuel from biomass waste such as paper and cardboard, is a promising solution for clean energy . " and added"
if fully developed this biofuel, it could simultaneously satisfy a portion of Global energy needs, but also fight against carbon emissions and dependence on fossil fuels . "
The research team used the Human Development Index of the UN to estimate waste production in 173 countries. These data were then correlated to the database "Earthtrends" to estimate the amount of fuel consumed in those countries. They found that 82.93 billion gallons of cellulosic ethanol can be produced from waste landfill in the world. And, substituting gasoline with biofuels, emissions global carbon could be reduced by about 29.2% to 86.1% for each unit of energy produced.
"
This could make cellulosic ethanol an important component of our renewable energy future
" concluded co-author of the study, Dr Lian Pin Koh of the & # 39; Polytechnic of Zurich (ETH).
